Introduction of Cable Insulation material

What is the insulation material?
Electrical insulating materials according to their chemical properties of commonly used is different, can be divided into inorganic insulation material and mixed organic insulation materials, insulation materials.Common inorganic insulation material has: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used for windings of motors, electrical insulation, switch backplane and insulator, etc.Organic insulating materials are: lac, resin, rubber, cotton, paper, jute, rayon, etc., mostly to cable manufacturing insulating paint, coating insulation of winding wire, etc.Hybrid insulation materials for the above two kinds of material processed into a variety of molding insulation materials, used as the base of the electrical appliances, shell, etc.
The application of insulating material
The role of the insulating material is charged part of the electric cable potential difference in the electrical equipment.Therefore should first insulating material has high insulation resistance and compression strength, and can avoid leakage and breakdown, accident.Second heat resistant performance is better, avoid long-term overheating and aging metamorphism;In addition, still should have good thermal conductivity, tide lightning resistance and high mechanical strength and easy processing, etc.According to the above requirements, the commonly used performance of the insulation dielectric strength, tensile strength, density, coefficient of expansion, etc.
